Mysterious Pluto’s true mystery revealed

nh-color-pluto-charon

Just about the time you think NASA’s groaning bureaucracy can groan no more, along comes a triumph to make it seem almost vivacious again —even if the triumph was managed by outsiders. And, in bringing distant Pluto (on right with moon Charon left) into closeup for the first time, the achievement reveals more mysteries than it explains. Making another distant (in miles and in time) visit likely, which should keep the groaning going for another decade or two.  (Click to biggerize.)

The Great Cholesterol Scam

UPDATED at bottom. Feds quietly overturn 40 years of bad advice.

I’ve had several family doctors over the years and most of them insisted that cholesterol, the so-called good and bad parts of it, was something to be concerned about—even to the extent of making dietary changes, etc. And then, way back in the early 1980s, I chanced upon a family physician who showed me my latest rather unfortunate cholesterol results and smiled and shrugged.

He said he didn’t think they were very much to worry about. He said he thought cholesterol as a health concern was over-rated. Unfortunately, he soon died (not of cholesterol-caused heart disease but of AIDS) and I wound up discovering how unusual he had been. Because I wound up with another doctor who was hell-bent on the subject. He was especially astounded to hear that I had started doing the Atkins diet on my own hook and was eating fatty meats and eggs every day. Like my grandparents who lived into their 90s.

Fatty meat and eggs, yowza! So he began badgering me about starting a course of statins, prescription drugs to lower my still rather bad cholesterol readings. I have always resisted prescription drugs and, remembering my old doc I resisted the statins and kept resisting them until me and the new guy got tired of arguing and parted. I found another doc who didn’t push statins and, by then, Atkins and other low-carb diets were becoming more or less respectable and the idea of eating fatty meat and eggs every day was much less objectionable.

I don’t know if the old statin-pusher has changed his tune or if he’s seen this new info, though you’ll have to read most of it to get the gist. They buried the lede for some reason.  Heh.  “In short. Cholesterol is healthy, saturated fat is healthy, salt is healthy and sugar is unhealthy”. Turns out there never was any hard evidence that cholesterol was even worrisome. Imagine that. It was on par with the federal government’s long-time insistence that low-fat diets were necessary, even if the increased sugar in low-fat diets could kill you. The latter is now blamed for our outbreaks of obesity and diabetes.

Admittedly, it’s hard to decide who to believe any more about anything. We’re lucky to have the Internet and its multiplicity of sources to compare and contrast. All I had before 1995 and the advent of the Web was my own stubbornness. It’s still a matter of homework and guesswork, however, especially if you tend, as I always have tended, to question authority. Which is a main reason I also discount claims of global warming/climate change, which you might call the new cholesterol. Although I must admit having Al Bore, Our Little Barry Hussein and the Dictator’s Club (aka the United Nations) all in the same GW/CC corner are excellent reasons to disbelieve in themselves.

UPDATE: From the WaPo: “The nation’s top nutrition advisory panel has decided to drop its caution about eating cholesterol-laden food, a move that could undo almost 40 years of government warnings about its consumption.”

That was in February. The move later turned up buried on page 91 of a 572-page federal dietary report. As of July, most of the snooze media, which seldom reads past the executive summary, still hasn’t caught on. When the feds overturn 40 years of bad advice they do it on tippy-toe. And they wonder why people don’t trust them.

Roughneckin’ in the patch

What I personally know of roughnecking wouldn’t fill a thimble. J.D., however, says as a kid he slept in the Doghouse while his father and other male relatives roughnecked the oil rigs. He pointed me to this good article in, of all places, National Review. Worth a look.

Reminded me of my dear grandfather who managed the oil trucks for the old Magnolia back in the ’30s, around Laredo, Alice and Freer. He cowboyed for a while near San Angelo but he was never a roughneck. I always understood that he admired some of them, though.

The Why And How Of Landing Rockets

“Even given everything we’ve learned, the odds of succeeding on our third attempt to land on a drone ship (a new one named “Of Course I Still Love You”) are uncertain, but tune in here this Sunday as we try to get one step closer toward a fully and rapidly reusable rocket.”

Good explanation, with pix and video, from SpaceX. Good luck, y’all.

UPDATE:  The SpaceX rocket Sunday never had a chance to attempt a landing. It blew up shortly after launch. The first loss in 19 tries. Thank goodness it wasn’t manned.

Firing the 1861 Springfield

This Hungarian fellow who styles himself capandball on the Internet has a really thick accent but if you listen closely you can get the gist of his description of the 1861 Springfield rifle-musket he’s firing here.

I would only note that most Confederates, if not most Yankees, preferred the British Enfield Pattern 1853 to the Springfield any time they could scarf an orphaned Enfield up off the battlefield.

Pity he’s not shooting at night so you could watch the impressive 3-feet of flame the black powder produces out the Springfield’s business end. Something that ended when cordite, or so-called smokeless powder, was introduced in 1889. Cordite also made the “fog of war” metaphorical, whereas it had long been literal with the copious amounts of smoke produced by black powder.

Google’s solar plant runs on natural gas

For four hours a day, no less. But that’s not the funniest part. The funniest part about this giant bird burner, is this:

“Because of alarmism based on computer model predictions of rising temperatures in 100 years, we’ve built a fossil-fuel fired solar plant which is already in trouble because of failed computer model predictions of the clouds over the next few years …

“Now, even the best solar energy conversion devices don’t operate 24 hours a day, or even 12 hours a day. Generally, eight hours a day or even less is the norm. And that has been cut down by clouds … so at present, dreaded fossil fuels are likely providing a third of the energy to fuel the plant.”

Google’s plant, of course, is fully subsidized by the Democrat federal government, i.e. your tax money at work, because it isn’t efficient enough to turn a profit. Which isn’t funny at all.

Why Fahrenheit is right and Celsius is wrong

It’s very logical, too logical for Frogs and others who insist on their contrary forms of measurement. Fortunately, despite all our Europhiles and their attempts to dissuade us from God’s measuring system, we’re still clinging to logic. And if our own Little Barry tries to force yours on us via executive order, we’ll just ignore his sorry arse.

Face it Froggies, there are those who have used the metric system and there are those who have walked on the moon. And every air traffic controller in the world today, including in Frogland, still uses our measurement for aircraft speed and altitude. And not yours.
